I have one MSI 6800GT , and had buy for it the cooler NV5 R2 . Today i have in order the Sapphire HD3850 AGP. I found some ppl speaking about 100% compatibility, of 6800 and ATI 3850 at sharing the same coolers . http://www.ncix.com/products/index.php?sku=14423&vpn=avc-nv5-r2&manufacture=arctic%20cooling I am thinking to replace the Sapphire cooler with the one of my Nvidia card . so if i can use the Arctic Cooling NV Silencer on it , it would be great , and saving of cash. Did any one had any info of success story s about that ?
